Optimization of processing method for Lonicera macranthoides of Guizhou by multi-index evaluation / 中草药

ABSTRACT

Objective To investigate the effects of different processing methods on the appearance, quality components and processing efficiency of Lonicera macranthoides that produced in Guizhou Province, in order to provide basis for the optimization of processing methods. Methods Eleven processing methods were used such as the traditional method group (sun drying, sun drying after steaming, drying in shade, and drying in shade after steaming), constant temperature drying group (50, 60, 70, and 80 ℃) and variable temperature drying group (50→60 ℃, 50→70 ℃, 50→80 ℃). Then the indicators such as color, aroma, moisture, total ash, acid insoluble ash, chlorogenic acid, total saponins, processing time, and drying rate were measured. Results According to all the indicators, the comprehensive correlation degree of the 50 ℃ and the variable temperature drying method was between 0.94 and 0.96, which was much higher than other methods, and the comprehensive correlation degree of 50→60 ℃ degrees was the highest, reaching 0.959 8. Conclusion In conclusion variable temperature drying method is a better processing method for L. macranthoides. This method can be used as an important technical means for large-scale processing.
